In describing the invention in detail reference will be had to the accompanying drawing wherein' like characters designate like and corresponding parts throughout the several views, and in which y Figure l is a perspective view of the darby.

Fig. 2 is a. side elevation of the darby showing parts in section. y

Fig. 3 is a section on the line 3-3 Fig. 2, and j Fig. 4L is a side elevation of one of the joints of two of the sections showing them spread or separated.

Referring more particularly to the drawing, 1 designates the darby structure as an entirety, which is composed of a plurality of sections, preferably threesections as indicated at 2, 3 and 4, comprising a center section 3 and the two end sections' 2 anelli. The end section`2 has .a handle 5 attached thereto in the usual manner. sections 2, 3 and 4: include blades 5 having straight edges and an outer smooth surface, and ridges 6 which are composed of sheet metal and are substantially circular places, such asin closets or the like.

ofy

The various shaped in cross section. The ridges 6 have downwardly extendinglegs 7 formed there-v on which engage and are secured to the upper surface of an attaching plate 8f as clearly shown in Figs. l and 3 of the drawing. The ridges 6 of the end sections 2 and d-have 'tubes 8 positioned therein and rojeeting outwardly therefrom for telescopic mounting in theridges 6 .of the intermediate section 5, for connecting the end sections 2 and 4to the intermediate section 3.

The blades of the intermediate section 3 k project beyond the end of the ridge 6 thereof, and the inner ends of the blades 5 of the outer sections 2 and l are `eut shorter than the ridge, as clearly shown in Fig. l of the drawing,'so that if it is desired, the

center section 3 may be used independent of the end sections 2 and I for work in close In reducing the invention to practice, certain minor features of construction, cornbination and arrangement ofv parts may necessitate alterations to vwhich the patentee is entitled provided such alterations are comprehended within the scope of what is claimed.

What is claimed is i In a plasterers darby, la center section, and end sections, said center and end sections comprising plates, ridges connected to v said plates and being hollow, tubes carried by the ridges ofthe end sections and telescopically mounted in the ridge of the center section for detachably connecting the end sections to the center` section, blades carried by each of said sections, the inner ends of the blades of said end sections stopping short of the ridges carried thereby, clamping plates for clamping said ridges to said blades, the portions of said clamping plates facing the ends of said center section extending beyond the ends of the blades of the end sections for gripping the protruding end of the blade of the intermediate section, the end of the blade of said vintermediate section projecting outwardly fromlthe end of the ridge and clamping plates carried thereby.

In testimony whereofI afliX signature in presence of two witnesses.
